My fiancée is very keen on arts and crafts. A light box was just what she needed to be able to trace patterns onto paper and cloth. This light box is cheap, safe and easy to build - I put it together in two hours. A key part of this design is maximum insulation between the internal components and the outside. This is essential with any design that involves mains electricity. As a consequence, all solder joints are located within the box, there are no metallic parts that protrude from the inside to the outside of the box, and the electrical cord was held in place with a cord grommet to prevent the cord being cut by back and forward motion.
